BACKGROUND OF THE INVENTION

The present invention relates to the technical field of weapon accessories, particularly to a weapon light.

Weapon lights are lights used together with weapons, which may assist users in identifying targets in low-brightness environments, allowing the users to illuminate the targets with the weapon lights while the weapons aim at the targets, and complete the shooting accurately. In general, the weapon lights consist of light bodies and light sources arranged within the light bodies, and the light bodies are connected onto the weapons, so that light from the light sources is consistent with a direction of barrels of the weapons.

However, the existing weapon light has a regular structure. There is a certain inconvenience when the weapon light fits together with the weapon. Particularly, if connecting notches used when the weapon light fits together with the weapon are sized to be consistent with the weapon, it is difficult to disassemble and assemble the weapon and the weapon light due to tolerances and other factors. If the connecting notches when the weapon light fits together with the weapon are sized to be slightly larger than the weapon, a clearance fit may be formed between the weapon and the weapon light after fitting, and the weapon light will shake and cause light from the light source of the weapon light to have an angular deviation from the direction of the barrel, which will affect the accuracy of the final shooting. In addition, the existing weapon light has poor universality in terms of the structure.

As shown in FIG. 1 and FIG. 2, a weapon light 100 according to an embodiment of the present invention includes a light body 10 and a clamping mechanism 30 connected onto the light body 10.

The clamping mechanism 30 is provided with a clamping groove 40 for clamping and fixing a weapon, so as to connect the light body 10 onto the weapon, assisting in lighting in a dark environment and facilitating a user to aim and shoot. The clamping mechanism 30 of the weapon light 100 of the present invention may move between a clamping position and an unclamping position to adjust the width of the clamping groove 40. As shown in FIG. 7, when the clamping mechanism 30 is in the clamping position, the width L1 of the clamping groove 40 is relatively small, so that it is possible to maintain a stable connection with the weapon and ensure that a light emitting direction of the light body 10 is consistent with a direction of a barrel. As shown in FIG. 8, when the clamping mechanism 30 is in the unclamping position, the width L2 of the clamping groove 40 is relatively large, that is, L2>L1, so that it is possible to conveniently place the weapon in the clamping groove 40 or take it away by the clamping groove 40, which makes the weapon light 100 and the weapon be more conveniently disassembled or assembled and the connection between the weapon light 100 and the weapon stable after fitting.

With reference to FIG. 3 and FIG. 4, the light body 10 shown includes a housing 12, a power supply 14 disposed within the housing 12, and a light source 16 electrically connected with the power supply 14.

The light source 16 may be any device which is energized to emit light, such as an LED and the like, which emit visible light for auxiliary illumination when electrically connected with the power supply 14. The power supply 14 may be a storage battery, a rechargeable battery and the like. The power supply may be a cylindrical battery, a block battery, and the like in terms of the structure. There is a single battery or there are multiple batteries. When there are multiple batteries, they may be arranged in a front-rear direction or a left-right direction or an up-down direction. In the illustrated embodiment, the housing 12 is of a substantially cylindrical structure, and a space 120 is formed inside the housing 12 for mounting the light source 16 and the power supply 14. The light source 16 is disposed near a front end of the housing 12. The power supply 14 includes two cylindrical batteries which are arranged in the housing 12 side by side in a left-right direction and are electrically connected with the light source 16 by electrodes 18 within the housing 12. Preferably, a light-transmitting cover 20 is connected to a front end of the housing 12, and the light-transmitting cover 20 may be made of glass, acrylic, and the like, which ensures that the light from the light source 16 may be all projected outwards while sealing the front end of the housing 12. In this embodiment, the light-transmitting cover 20 is of a flat sheet structure, which plays roles in sealing and light transmission. In other embodiments, the light-transmitting cover 20 may have a certain radian to play a role in condensing or diverging light.

A rear cover 24 is rotatably connected to a tail end of the housing 12 by means of a pivot 22, and the electrode 18 is arranged at an inner side of the rear cover 24. When the rear cover 24 is closed, the electrode 18 is in contact and connection with the power supply 14, the power supply 14 is connected with a power supply circuit of the light source 16, and the light source 16 may produce light illumination. On the contrary, when the power supply 14 needs to be taken out, for example, when it is necessary to replace the battery if the battery power is insufficient or the power supply is not used for a long time, the rear cover 24 is opened to separate the electrode 18 from the power supply 14 and the power supply circuit of the power supply 14 to the light source 16 is disconnected. As shown in FIG. 2, a clamping block 26 is formed on a rear end of the rear cover 24 in a protruding manner, and a clamping hook 28 is connected onto the housing 12. When the rear cover 24 is rotated to be closed with the housing 12, the clamping hook 28 is hooked and buckled on the clamping block 26 to keep the rear cover 24 and the housing 12 in a closed state, ensuring that the power supply 14 is stably electrically connected with the light source 16. In the illustrated embodiment, a bottom portion of the rear cover 24 is hinged with the housing 12, and the clamping block 26 is disposed on a top portion of the rear cover 24. Preferably, the clamping hook 28 is rotatably connected with the housing 12. When the rear cover 24 is closed, the clamping hook 28 is rotated to be horizontal, and the clamping hook 28 and the clamping block 26 are buckled to fixedly connect the rear cover 24 with the housing 12.

As shown by a dotted line in FIG. 4, when the rear cover 24 needs to be opened, for example, when the battery needs to be taken out or replaced, the clamping hook 28 is rotated to be upright or inclined to separate it from the clamping block 26, which brings the convenience for the operation. It should be understood that the clamping hook 28 may be disposed on the rear cover 24, and correspondingly, a clamping block 26 may be disposed on the housing 12. In addition, the rear cover 24 and the housing 12 may be connected in other ways, such as screwing, tight fitting, and the like, which are not limited to specific embodiments.

With reference to FIG. 5 and FIG. 6, the clamping mechanism 30 includes a first clamping member 32 and a second clamping member 34 arranged at an interval, and a driving member 36 driving the first clamping member 32 and the second clamping member 34 to move relative to each other.

Both the first clamping member 32 and the second clamping member 34 are substantially of a strip structure and are arranged in parallel to a lengthwise direction or an axial direction of the light body 10. Preferably, the first clamping member 32 and the second clamping member 34 are parallel, and the clamping groove 40 for clamping the weapon is formed between the first clamping member 32 and the second clamping member 34. In this embodiment, the first clamping member 32 is a fixed member, which is integrally connected with the housing 12 of the light body 10. In other implementations, the first clamping member 32 may be fixedly connected onto the housing 12 of the light body 10 by a fixing member such as a screw after being individually formed. The second clamping member 34 is a movable member and is slidably disposed on the housing 12. Correspondingly, the housing 12 is provided with a sliding groove 124 for the second clamping member 34 to move, and the second clamping member 34 is moved towards or away from the first clamping member 32 in a left-right direction or a widthwise direction of the light body 10 under an action of the driving member 36.

The driving member 36 includes a driving rod 360 and a driving wrench 362 rotatably connected with the driving rod 360. The driving wrench 362 is arranged on an outer side of the first clamping member 32 to facilitate the operation of the user. An outer end of the driving rod 360 is connected with the driving wrench 362 and an inner end thereof is in transmission connection with the second clamping member 34 after passing through the first clamping member 32, so that the second clamping member 34 is driven to move by operating the driving wrench 362. The driving wrench 362 includes a rotating portion 363 and an operating portion 364 extending outwards from the rotating portion 363. The rotating portion 363 is pivotally connected to the outer end of the driving rod 360 by means of a shaft 366. The shaft 366 is eccentrically arranged with respect to the rotating portion 363, so that when the rotating portion 363 rotates around the shaft 366, a separation distance between the shaft 366 and the first clamping member 32 may be changed; and further the second clamping member 34 is driven to move relative to the first clamping member 32, so that the width of the clamping groove 40 between the first clamping member 32 and the second clamping member 34 is changed.

In the illustrated embodiment, the driving rod 360 extends laterally in a left-right direction and is arranged perpendicular to the first clamping member 32 and the second clamping member 34, the shaft 366 is arranged in a vertical direction, and an outer peripheral surface of the rotating portion 363 of the driving wrench 362 includes an arc-shaped surface 368 and a flat surface 369. The arc-shaped surface 368 is preferably a semi-cylindrical surface, and the flat surface 369 is tangent and smoothly transitions to the arc-shaped surface 368. The operating portion 364 extends obliquely outwards from the flat surface 369. Preferably, anti-slip ribs 365 are formed on the operating portion 364. As shown in FIG. 7, in a normal state, the driving wrench 362 is substantially parallel to the first clamping member 32, the flat surface 369 of the rotating portion 363 abuts against an outer wall surface of the first clamping member 32, and a relatively large separation distance D1 is formed between the shaft 366 and the first clamping member 32.

As shown in FIG. 8, when the driving wrench 362 is rotated 90 degrees clockwise in a certain direction, the driving wrench 362 is substantially perpendicular to the first clamping member 32, and the arc-shaped surface 368 of the rotating portion 363 abuts against the outer wall surface of the first clamping member 32, and a relatively small separation distance D2 is formed between the shaft 366 and the first clamping member 32, that is, D2<D1. In contrast, the flat surface 369 of the rotating portion 363 abuts against the first clamping member 32, and a surface contact is formed between the flat surface 369 and the first clamping member 32, wherein the surface contact is stable in form and is kept for a long time. When there is no acting force to rotate the driving wrench 362 in an opposite direction, the rotating portion 363 does not rotate by itself. The arc-shaped surface 368 of the rotating portion 363 abuts against the first clamping member 32, and a line contact is formed between the arc-shaped surface 368 and the first clamping member 32. The arc-shaped surface 368 may be rotated by a small acting force, which is an intermediate form and brings the convenience for subsequent resetting.

Preferably, elastic members 38, such as springs, are provided between an inner side of the second clamping member 34 and the housing 12. In this embodiment, the elastic members 38 are arranged in pairs, and are respectively arranged near two ends of the second clamping member 34 to ensure that the second clamping member 34 is evenly stressed. Preferably, guiding columns 342 extend vertically from an inner side of the second clamping member 34, and correspondingly, the housing 12 is provided with guiding holes 122. The guiding columns 342 are inserted into the guiding holes 122 to guide a movement of the second clamping member 34 relative to the first clamping member 32. Preferably, the elastic members 38 are sleeved on the guiding columns 342, one ends of the elastic members 38 abut against or are connected to the second clamping member 34 and the other ends thereof abut against or connected to the housing 12. As shown in FIG. 7, in a normal state, the elastic members 38 are compressed and form an outward bias to the second clamping member 34, that is, forms a bias away from the first clamping member 32.

When the weapon light 100 of the present invention fits with a weapon, an action force is applied to the driving wrench 362 to make it rotate outwards, for example, rotate clockwise about 90 degrees as shown. At this time, as shown in FIG. 8, since the rotating portion 363 is eccentrically connected with the shaft 366, the rotating portion 363 rotates to cause the shaft 366 to move towards the first clamping member 32. A distance between the shaft 366 and the first clamping member 32 is reduced to D2. Under an action of the elastic members 38, the rotating portion 363 rotates to cause the second clamping member 34, the driving rod 360 and the driving wrench 362 to move outwards relative to the first clamping member 32, so that the arc-shaped surface 368 of the rotating portion 363 always keeps abutting against the first clamping member 32. Due to a movement of the second clamping member 34, the width of the clamping groove 40 between the first clamping member 32 and the second clamping member 34 is increased to L2. As such, the weapon may be easily inserted into the widened clamping groove 40.

After the weapon is placed in the clamping groove 40, an action force is applied again to the operating portion 364 of the driving wrench 362 to make it rotate in an opposite direction, for example, rotate counterclockwise about 90 degrees. At this time, as shown in FIG. 7, the driving wrench 362 returns to a position in parallel to the first clamping member 32, a flat surface 369 of the rotating portion 363 abuts against the first clamping member 32, the rotating portion 363 rotates to cause the shaft 366 to move away from the first clamping member 32, and a distance between the shaft 366 and the first clamping member 32 is increased to D1. Meanwhile, the shaft 366 drives the second clamping member 34 by means of the driving rod 360 to move towards the first clamping member 32 and compress the elastic members 38 again, so that the entire clamping mechanism 30 is reset. Due to the movement of the second clamping member 34, the width of the clamping groove 40 between the second clamping member 32 and the first clamping member 32 is reduced to L1, and the weapon in the clamping groove 40 is clamped, the stable connection between the weapon light 100 and the weapon is ensured, and the consistency of the light emitting direction of the weapon light 100 with the direction of the barrel is guaranteed.

When no weapon light 100 is needed on the weapon, it is necessary to rotate the driving wrench 362 again to a position as shown in FIG. 8, so as to increase the width of the clamping groove 40 between the first clamping member 32 and the second clamping member 34 to L2, so that the weapon may be easily taken away by means of the enlarged clamping groove 40, and thus the weapon light 100 of the present invention and the weapon are extremely convenient to disassemble and assemble. Meanwhile, it is possible to ensure that the weapon light 100 is tightly and stably connected with the weapon by reducing the width of the clamping groove 40 after the weapon is assembled, to guarantee that the light emitting direction of the weapon light 100 is consistent with the direction of the barrel, and to prevent from affecting the aiming due to the shaking of the weapon light 100. In addition, the width of the clamping groove 40 is changed by the rotation of the driving wrench 362, and the arc-shaped surface 368 of the driving wrench 362 may minimize the friction during the rotation to make the operation more labor-saving. By means of the flat surface 369 of the driving wrench 362 and the first clamping member 32, the stability during clamping of the weapon is effectively guaranteed, and the weapon light 100 is prevented from loosening by automatic rotation of the driving wrench 362 due to slight touching or shaking to affect the use of the weapon.

Preferably, a first slot 320 is formed in an inner wall surface of the first clamping member 32, that is, a wall surface facing the second clamping member 34. Correspondingly, a second slot 340 is formed in an inner wall surface of the second clamping member 34, that is, a wall surface facing the first clamping member 32. The first slot 320 and the second slot 340 extend in parallel to a lengthwise direction of the light body 10 and penetrate through the first clamping member 32 and the second clamping member 34, respectively, so that the weapon may be inserted into the first slot 320 and the second slot 340 in the lengthwise direction of the light body 10. Due to the arrangement of the first slot 320 and the second slot 340, the weapon may be initially positioned during the fitting, and may not be deviated or misaligned during the clamping. In addition, the weapon is limited in an up-down direction to ensure the accuracy and the stability of the position of the weapon after the fitting. It should be noted that when the first slot 320 and the second slot 340 are provided, the width of the clamping groove 40 refers to a width between the first slot 320 and the second slot 340.

Preferably, the clamping mechanism 30 further includes an adjusting member 39. In this embodiment, the adjusting member 39 is a nut, and the driving rod 360 is a screw rod. A screwing length of the nut and the screw is used to adjust the width of the clamping groove 40 between the first clamping member 32 and the second clamping member 34. As shown in FIG. 5 and FIG. 6, the adjusting member 39 is arranged at a center of the second clamping member 34 in a penetrating manner and is positioned between two elastic members 38. An inner end of the driving rod 360 is screwed within the adjusting member 39, and a head of the adjusting member 39 protrudes from an outer side of the second clamping member 34 to facilitate the operation of the user. When the adjusting member 39 is rotated outwards, the screwing length of the adjusting member 39 and the driving rod 360 is shortened, which increases the total length of the driving rod 360 and the adjusting member 39. On the contrary, when the adjusting member 39 is rotated inwards, the screwing length of the adjusting member 39 and the driving rod 360 is increased, which reduces the total length of the adjusting member 39 and the driving rod 360.

With reference to FIG. 8, when the adjusting member 39 is rotated outwards, the second clamping member 34 moves outwards relative to the housing 12 under an action of the elastic members 38, so that the clamping groove 40 between the first clamping member 32 and the second clamping member 34 is enlarged to L10 in a normal state to adapt to a weapon with a larger size. Similarly, the width of the clamping groove 40 may be further increased by rotating the driving wrench 362, so that the weapon with the larger size may be conveniently put into the clamping groove 40. After the weapon with the larger size is inserted, the width of the clamping groove 40 may be returned to L10 by reversely rotating the driving wrench 362, so that the weapon is clamped. It should be understood that the adjusting member 39 may be rotated inwards to drive the second clamping member 34 to move inwards relative to the housing 12 and further compress the elastic members 38, so that the width of the clamping groove between the first clamping member 32 and the second clamping member 34 is smaller in the normal state to adapt to a weapon with a smaller size. In this way, the weapon light 100 of the present invention may match weapons of different specifications, and is universal.

In the foregoing embodiment of the weapon light 100 of the present invention, when the second clamping member 34 moves towards the first clamping member 32, the elastic members 38 are compressed, and the elastic members 38 drive the second clamping member 34 to move away from the first clamping member. 32. It should be understood that when the second clamping member 34 moves towards the first clamping member 32, the elastic members 38 are stretched, and the elastic members 38 drives the second clamping member 34 to move away from the first clamping member 32. Alternatively, when the second clamping member 34 moves away from the first clamping member 32, the elastic members 38 are compressed or stretched, and the elastic members 38 drive the second clamping member 34 to move towards the first clamping member 32. In addition, the shape and the size of the driving wrench 362 may be set below as required: when the driving wrench 362 is rotated to its arc-shaped surface 368 to abut against the first clamping member 32, the distance between the shaft 366 and the first clamping member 32 is increased and further the width of the clamping groove 40 is reduced; and when the flat surface 369 of the driving wrench 362 abuts against the first clamping member 32, the distance between the shaft 366 and the first clamping member 32 is reduced and further the width of the clamping groove 40 is increased.

It should be noted that the present invention is not limited to the above-mentioned embodiments.
